THEODORE KAUFER, OF BROOKLYN, NEW YORK.

GAS FIRE-KINDLER.

Application filed December 16, 1916.

To all whom it may concern:

Be it known that I, THEODORE KAm ER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Fire-Kindler, of which the following is a full, clear, and exact description.

This invention relates to stoves and furnaces and has particular reference to a novel form or adaptation of fire box grate.

Among the objects of the invention is to provide a grate adapted to support a bed of coal or other kind of fire, said grate comprising a plurality of horizontal bars made tubular for the conveyance of gas for'the purpose of generating heat-either for cooking, heating or other purposes for which the stove or furnace is intended, but more particularly for the kindling of a body of fire in the coal, wood, or the like supported upon the grate.

Another object of the inventionis to provide a combined fuel supporting grate and a gas-igniting means, the same comprising a main or body, portion and an auxiliary portion lying directly thereover, each portion having longitudinal bars or their equivalent registering directly with similar bars of the other portion, means being provided to prevent lateral separation of said bars with respect to each other.

lVith the foregoing and other objects in view, the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to theexact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a vertical longitudinal section of my improvement applied to what may be regarded as a conventional type of coal range, the section being on the line 1-1 of Fig. 2;

Fig. 2 is a horizontal section on the line 9-2 of Fig. 1; and I Fig. 3 is a vertical. transverse section on the line 33 of Fig. 1.

Referring now more particularly to the drawings, I show a stove having a fire box 10, a top 11, and an ash pit 12. These parts Specification of Letters Patent.

obviously may be of any suitable size, design or construction.

13 indicates a trunnion secured on a fixed support 11 between the fire box and the ash pit and having a transverse horizontal axis. In alinement with this axis, the opposite side of the stove is provided with a hole 15 forming a bearing for a trunnion 16, constituting a part of the grate.

The grate referred to comprises a main lower portion or body 17 and a separate or separable auxiliary portion or top 18. The trunnion 16 is preferably cast integral with the body 17 and projects horizontally from one end thereof. The axis of the trunnion, however, while being in the axis ofthe fixed trunnion 13, is preferably located at one side of the median line of the grate, so that the grate has a normal tendency to lie in a horizontal position through the cooperaa tion of the relatively movable and fixed lugs 19 and 20 carried respectively by the grate body and the stove structure. The grate, however, is free to be rotated in one direction through a shaker applied to the outer end of the trunnion 16 for the usual purposes.

21 indicates a gas supply pipe leading from any convenient source of supply, the

flow of the gas being controlled by a stop cook 22 in any convenient manner. The nozzle portion 23 of the gas pipe is fitted securely within the stove just below the trunnion 16, and'is shown as comprising a plurality of outlets 24 and 25 having their mouths lying in substantially the same plane and approximately at the end of the body portion 17 of the grate.

Said body 17 is made preferably as a casting comprising a series of parallel bars 26 and 27. These bars are all connected at the ends of the grate through cross bars 28 and 29, forming a unitary rigid structure, including the aforesaid trunnion 16 and an inverted U-shaped bearing 30, cooperating with the fixed trunnion 13.

The bars 27 are shown as hollow or trough-shaped with open tops, each bar being substantially U-shaped in cross section. At the gas supply end of the grate, each of the bars 27 is provided with a gas intake 31, extending with its axis in a horizontal direction beneath the end bar 28 and in axial alinement with a nozzle Zlor 25. When, therefore, the gas is admitted through the pipe 21 to the grate, it is received within the bars 27 and conveyed thus lengthwise of the grate. For convenience of construction the body 17 of the grate is made with a smooth upper surface, the surfaces of the several bars lying in the same plane.

The top portion of the grate is of the same design and size as the body portion, and hence comprises bars 26 and 27 corre sponding to the solid and hollow bars respectively of the body. I provide also c011- necting end bars 28 and 29. The lower surfaces of the bars of the top 118 all lie approximately in the same plane and flatly against the upper surface of the body 17 with th exception that the bars 27 are concaved on their lower surfaces and have their edges serrated, forming lines of gas discharge openings32. The top 18 is readily removed from the body 17 either for the purpose of cleansing the grate or for interchange or repair. As a matter of fact in practice, the top portion being subjected to the greatest heat, is theonly. part of the device subject to severe deterioration and can be renewed at a'very small cost. Any suitable number or arrangement of lugs 3:3 and 34: may be provided to prevent the lateral sliding of the top 18 when the grate as a whole is rotated as above described.

In view of the construction disclosed herein and described in detail above, the operat'ion may be briefly set forth as follows;

lVith any suitable fuel, such as wood,coal, coke, or the like, supplied to the fire box and supported upon the grate, the gas being turned on and admitted into the grate for distribution through the jet holes 82, a match applied beneath the grate will ignite the gas which may be left burning for several minutes according to the density of the fuel, but insuring that the fuel will be Well started and then the gas will be shut off at the stop cook 22. No further attention need then be paid to the gas until the fire is again to be kindled. The oscillation or shaking vof the grate .may take place independently of the fixed gas nozzle 23.

I claim:

The combination with a solid fuel burner and a gas supply device secured rigidly thereto, said gas supply device comprising a plurality of outlets, of a fuel supporting grate having end bearings in and on oppo site sidesof the burner, said grate comprising a main body portion having a plurality of hollow bars with intakes located normally directly'opposite the outlets ofthe gas supply nozzle and below the axis of the grate, the upper surface of the body being smooth, said grate also including top having'bars lying directly over and in contact with the body bars, said top bars cooperating with the hollow bars being provided with other to prevent lateral displacement of the grate bars with relation to each other.
